The adaptive cruise in the Honda Accord (ADAS) even uses the power steering to keep you exactly in your lane on the motorway. The Lexus LS can park itself. Also the (prototype) BMW that drove itself around the Topgear test track was pretty interesting. Seems like all the major manufacturers are putting a lot of effort into these autopilot style systems.

Its only a matter of time before you set your destination on the satnav and it drives you there. It will make the whole aspect of insuring your car rather interesting! Can you just imagine the lawsuits when this stuff goes wrong...
